我创建了一个基本的Tic-Tac-Toe类，它显示9个按钮，显示随机图像（每个运行时间 - 不同的序列）。主要方法是另一个测试类，它只是一个框架创建者。除此之外，我想添加一些事件处理。我已将'ActionListener'添加到按钮＆amp;想在'actionPerformed'方法中添加一些逻辑。每次我点击任何按钮，它应该按照X - >的顺序连续改变图像。 O - ＆gt;空白 - ＆gt; X.我不确定哪种逻辑适合于按上述顺序翻转图像（例如for-loop，switch等）。代码如下：
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class TicTacToe extends JFrame {
public JButton[][] labels = new JButton[3][3];
public ImageIcon[] icons = new ImageIcon[3];
public int r, c;
public TicTacToe() {
// TODO Auto-generated constructor stub
setLayout(new GridLayout(3, 3));
for (r = 0; r < labels.length; r++) {
for (c = 0; c < labels.length; c++) {
int random = (int)(Math.random() * 3 + 0);
System.out.println(random);
JButton s = new JButton(this.icons[random]);
this.add(s);
this.labels[r][c] = s;
if (random == 0) {
System.out.println("Cross Image Icon");
labels[r][c].setIcon(new ImageIcon("C:\\Users\\yogesh\\workspace\\hw3pandarey\\src\\hw3pandarey\\cross_symbol.gif"));
add(labels[r][c]);
validate();
} else if (random == 1) {
System.out.println("Not Image Icon");
labels[r][c].setIcon(new ImageIcon("C:\\Users\\yogesh\\workspace\\hw3pandarey\\src\\hw3pandarey\\zero_symbol.gif"));
add(labels[r][c]);
validate();
} else if (random == 2) {
System.out.println("Keep it blank");
labels[r][c].setIcon(new ImageIcon());
add(labels[r][c]);
validate();
}
labels[r][c].addActionListener(new ButtonListener());
}
}
} // end of TicTacToe constructor
public class ButtonListener implements ActionListener {
public void actionPerformed(ActionEvent e) {
} // end of actionPerformed method
} // end of ButtonListener class
} // end of TicTacToe class
import javax.swing.*;
public class TicTacToeTest {
public static void main(String[] args) {
TicTacToe frame = new TicTacToe();
frame.setTitle("Let's play a random tic-tac-toe game !!!!!");
frame.setSize(400, 400);
frame.setLocationRelativeTo(null);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
} //end of main method
} // end of test class

您可以使用setText方法在JButton上放置X或O，就像这样。 如果变量知道它是X还是O转，你需要添加所有内容。 希望这有帮助
public class ButtonListener implements ActionListener
{
public void actionPerformed(ActionEvent e)
{
Object src = e.getSource();
for(int i = 0; i < 3; i++) {
for (int j = 0; j < 3; j++) {
if(src==labels[i][j]&&labels[i][j].getText()==""){
//if X turn
labels[i][j].setText("X");
}
//if O turn
//labels[i][j].setText("O");
}
}
}// end of actionPerformed method
} // end of ButtonListener class

所以我添加了＆＃39; switch＆＃39;内部＆＃39;为＆＃39;循环，这样每次单击按钮时，它都会按特定顺序翻转图像。我希望相同的图像不翻转任何文字，所以我使用了＃set; con（）＆＃39;方法。为此，我在主类中创建了三个ImageIcon对象。为三种不同的情况添加了一个计数器＆amp;它不断循环。
我的最终答案代码如下：
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class TicTacToe extends JFrame
{
public JButton[][] labels = new JButton[3][3];
public ImageIcon[] icons = new ImageIcon[3];
byte value=0;

public ImageIcon o= new ImageIcon("C:\\Users\\yogesh\\workspace\\hw3pandarey\\src\\hw3pandarey\\zero_symbol.gif");
public ImageIcon n= new ImageIcon("");
public TicTacToe()
{
// TODO Auto-generated constructor stub
setLayout(new GridLayout(3,3));
for(int r=0; r<labels.length ; r++)
{
for(int c=0; c<labels.length ; c++)
{
int random = (int)(Math.random() * 3 + 0);
System.out.println(random);
JButton s = new JButton(this.icons[random]);
this.add(s);
this.labels[r][c] = s;
if(random == 0)
{
System.out.println("Cross Image Icon");
labels[r][c].setIcon(new ImageIcon("C:\\Users\\yogesh\\workspace\\hw3pandarey\\src\\hw3pandarey\\cross_symbol.gif"));
add(labels[r][c]);
validate();
}
else if(random == 1)
{
System.out.println("Not Image Icon");
labels[r][c].setIcon(new ImageIcon("C:\\Users\\yogesh\\workspace\\hw3pandarey\\src\\hw3pandarey\\zero_symbol.gif"));
add(labels[r][c]);
validate();
}
else if(random == 2)
{
System.out.println("Keep it blank");
labels[r][c].setIcon(new ImageIcon());
add(labels[r][c]);
validate();
}
labels[r][c].addActionListener(new ButtonListener());
}
}
} // end of TicTacToe constructor
public class ButtonListener implements ActionListener
{
@Override
public void actionPerformed(ActionEvent e)
{
// TODO Auto-generated method stub
for(int r = 0; r < 3; r++) {
for (int c = 0; c < 3; c++) {
if(e.getSource()==labels[r][c])
{
value++;
value%=3;
switch(value)
{
case 0:
labels[r][c].setIcon(n);
break;
case 1:
labels[r][c].setIcon(x);
break;
case 2:
labels[r][c].setIcon(o);
break;
} // end of switch
}// end of 'if'

} // end of outside for loop
